The sliding fence that sits on top of the resaw 10' ball bearing table allows for adjusting the thickness of cut and if blade drift is a issue it allows for that as well. The 17" saw with the 1" blade doesn't drift like the smaller blades will do

Here is a picture of the resaw fence. The 10 foot ball bearing table is not built yet. Last night I took the factory bolts on the Bandsaw table and made attachments for the 10' table. The blue T track and knob allows for easy thickness adjustment with out having to reposition the log on the sled. Of course first 2 cuts I will straight line 2 edges first then saw off the lumber slabs. In the past I just ran the boards through the planner as my jointer is only 6" wide.

I really enjoy this stuff the pictures shown in this topic are great ideas. Enjoy seeing what other ideas are out there. I learn so much from asking questions and doing these things.

Roughed in the Bandsaw Sled table support this weekend. Trying to keep all the functions of the factory saw still available even with the 10' 28" table attached. I have a 1" spot the original fence won't lock down (I would have to use a clamp to lock it down there) but the rest of it will work and can be adjusted.

I am just adding pictures to this link. So this weekends work is nested down on this page a bit

I am getting excited to put down the deck on the resaw table and get the miter gauge line up and roller bearings installed. This table will be removed when no logs are on property. The 17" bandsaw is handy for cutting stuff.

Installed the top deck with the 5/8 bearings. Now to tweak it and install adjustable table legs to hold the table up until I get a hydraulic support table under them. Between the two pump tables I should be able to get the 200 pound logs up there and roll them onto the sled with out lifting them with my back so much...that is the plan.

Since this is all a portable setup the clamps maybe the best option as minor adjustment may need to be done as I go.

Used this long 10' long table and wheeled in my drill press into the slot where the bandsaw is supposed to go and drilled forstner bit holes with the drill press on this 8' long piece of plywood. The table being made out of 1/4 is easily lifted up and shifted off of the hydraulic wooden tables. I can turn the carts around and move the table around in the shop with not to much work.

Resawed 3 12"x 48" logs yesterday. About wore me out. Going to install a winch tonight and give the last log a little push with a button. Didn't think I would need it but those 200 pounders were heavy even with the roller bearings and the lube on the bandsaw table. It was all I could do to push the sled across the table. It did get easier as I cut off 1" x 10" x 48" long walnut boards.


Was very pleased. This was my best results withmy total resawing experience some 50 logs. 8 of them Walnut and about 4 of them red Oak and the rest Cedar. (this doesn't count the bandsaw mill I ran for about 5 days up in Alaska but that was a horse of a different color. It was made for that)


The sled will get a temp winch install and will see how it goes. I have a video segment of this process. If I can get the 3 cameras to play at the same time. HA!

The winch pulled it to fast and having only one log to saw up I only cut one board using the winch. If I pressed the winch button for a 1/10 of a second the saw would not get over loaded. I could slow the feed rate down using a 3 to one pulley and that might work but for now I just pushed it on through.


Nice stack of 8" wide Walnut 1" thick and 42" to 48" long boards. I used some 1/2" plywood and ripped up some 1/2" x 1" x 26" long sticker sticks about 30 of them. Will dip the ends of the boards in paraffin wax tonight. There are a few more smaller boards to rip out of the logs. Won't need the resaw table for those. The table is easy to attach to the saw. Just pull it out one person can move it around shown behind the bandsaw. Place it on the two portable pump carts shown with the barked logs on them. Pump them up and roll into position. Then use 4 hand clamps and clamp into position. This was a fun project that took me about 2 weeks to complete over a few hours here and there. I will say the dust deputy 4" and the 2" were a blessing in this. I had max suction and clean up was a breeze. Shop vac filters are still clean after all this resawing and clean up.

I dipped the ends of the 35 walnut boards into a banna bread pan that had hot parifin wax in it. I had two pots on hot plates keeping the wax hot and would pour it in the bannna bread pan as the wax was consumed by the ends of the boards. Restickerd them and they will be moved into a shed in the back yard for a year. This was a fun project. I learned a lot.

Here is a video on the sled.

Here is a 48 minute of a bunch of take outs of resawing 4 logs. One may need to use the slider to get past some of it.!

I didn't get the winch perfected it was too fast. Figured in the future a pulley 3 to 1 speed reducer would work. Maybe. It may take a hand crank to allow for fine tuning it.

I have never seen those ball bearings in action .....

They seem like they do not roll very smoothly...... I donno, but does the added weight of the log decrease or increase they pushing effort?
I started this thread to show my approach with a simple sled and the roller supports, so I have no other reference for the effort needed to push the log thru. I do know that without a sled, just pushing a 10" thick piece does require some effort.



A suggestion, if you make another version would be to use a HPL like Formica on one or both of the sliding surfaces and with a spray silicone or wax, I think it will slide very easily.



Another suggestion regarding the 2 camera Video which I found difficult to watch in either of the 2 views. A person who could video you while you operated the sled would, in my opinion, be much smoother and easier to watch. A head mounted camera is just too jumpy to follow because your head moves each time you look at something else.


You have given the whole concept of milling with a vertical bandsaw a lot of thought and that comes thru loud and clear. It is a complex operation in some ways, but simple in others. I like the idea of having a long removable rail which is not attached to the saw permanently. This frees up the saw for other operations. I do know that lifting heavy logs is dangerous and cumbersome and any means other than using brute strength is great! I appreciate all your efforts.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Sawed up 5 four foot long walnut logs into 1"x 10"x 48" lumber. Those logs were 12" around and weighed in 200 pounds my best guess... I couldn't pick them up. Just one end at a time and lots of huffing and puffing.

Here is a link to my shop updates the resaw table and links to the youtube videos using the resaw table and sled are there.

http://readyrangers.tzo.com/2019Shop...update2019.htm

Pictures how the sled the stack of walnut stickered (ends dipped in hot wax) and the resaw table off of the bandsaw. Last night I cut the table in half so I could move and store it when not in use. It is held onto the bandsaw with clamps. Takes about 5 minutes to put on the saw. It did a good job. I used a winch but it was to fast. Need to slow that down to make that work.

My chesty camera was dead. Sorry about the video footage. Always can do better with that. It would be nice to have someone video but not a lot of support there. Ha! You should see the parts I cut out. I had almost 3 hours of footage and it took more time to trim most of that out.
I could stream line the whole process a bunch in many ways. Yet it is what it is. A one man shop in a 2 car garage. It was fun and I enjoyed it. If I built another one it would have some more changes to it. Yet it worked very well as it was. I need to get a remote for the dust collections and I spent as much time cleaning off the table removing debris and dust as I did resawing.


The weight of those logs at 4' long are the factor with friction. When they are 70 or so they feel like feathers! 200 pounds and things get factored up.


Thanks for your interest in this. I enjoyed it and gleaned a lot from the other videos and tips.

Here is a shorten video and I edited out some dead spots but it's still 43 minutes so use the slider. Video quality is informative but it's certainly not very good as my camera that I carried will make you sea sick.
