Thread: bandsaw pics for BobL

The pics are bloody fantastic Peter.

And so nicely laid out too!

Sure got the old juices flowing.

Back in early 2007 I scored a 2.4 m long set of rollers from a bit of dumpster diving.

I was thinking of popping out every second roller and making up a second set of rollers so I have equal length in and out feed rollers for my 19" bandsaw. Then do the same thing as you did to your fence. Looks like a good summer project to me.

Glad u like, I like to have a bit of a logical sequence to my pics, maybe its the half baked gingerbeer in me
I got the call from the tree loppers this morn, so I got a small silky oak log with 2 100 thick slabs which I cut into 100x100.
Took some pics, just about to add them to post
Ahh a good bit of dumpster diving there and a good find

The thing I found with slabs on the rollers was that unless the slabs r flat and even they wernt too good when I was trying to cut an edge off or cut to a size, the slab moves and bounces around a fair bit and any sort of packing doesnt work, urs might be better if u keep them closer together, mine r about 300 apart with cross supports which the slabs tended to get stuck on, the slab on the sleds was much better as I could put packing in if needed,clamp to the sleds if needed, sleds move a lot easier, self wieght can hold them in place, I can adjust the position of the slab on the move if I need to, no cut line to try and cut to, I nearly dont need the rollers for most of what I do but they r still good for flat boards that r to be ripped or resawn, this has been my experience.

Sleds that roll on the rollers might be the go, I think there have been a few posts along this line
I reckon u will tackle any probs as u find them and sort it in a typical BobL style

Ill add the pics here
4' thick slab about 300 wide on sleds

both edges cut off ready to cut 100 wide

need to clamp the slabs with a lot of wieght hanging off the sled, can over balance and fall off

not much colour in the local well watered variety, but they do come up allright, a light tan sort of shade

Peter

Peter that is a great look at your set-up.

Now, I might have missed this , how big is your saw, what size blade & type. and what brand.??

I have some stuphph that I want to slab when I get back home. Nowhere near that size but I like the look of how your planks come out. I did some without the advantage of a sled and the results were not what I had hoped for.

Thanks for the advice Pete, which all makes a lot of sense. I think I might go for sleds on the rollers.

My bandsaw started life as a CarbaTec 19" 2hp arrangement
Mods since then....
3kw (4hp) 3ph motor
faster blade speed... 3000 and 3900 ft/min I think, working from memory here
completely different blade guide system
better dust extraction
longer better fence
the single most important improvement was the lennox woodmasterB blade 1 1/4" wide...like chalk and cheese compared with the horrible thing that came with machine

I have a couple of posts in the bandsaw forum where I go into a bit more detail but that's basically it

Bob, I think it was Dia densie (spelling?) that had a sled on roller setup or maybe not something painted yellow seems to ring a bell, anyway in the BS forum a while back now.
The next mod is gonna be a longer roller as this will support wider boards better, at least 6" long, I would suggest if u r going to incorporate a roller/s on the xmas project make them 6" or longer

A few more pics cutting up lumps of raintree this morning...

Y I like the sled/s.... I can plonk a bit roughsawn on it, line the blade up, line the exit point up by eye, pack as required, decide whether to clamp or not then saw just like this

Pete, thanks for the detailed reply - good photos too.

That's what mine is.

OK - how did you change the speed? Was it a pulley change?

By rollers do you mean sleds? or the roller wheels under the sleds?

My rollers are 16" wide.

That sure is nice looking lump of stuff.

Sorry Bob, I wasn't real clear there, the roller/s I was refering to was what we might call a resaw roller, the one I currently have setup is only 50mm wide, I was thinking something more like this, I picked these up somewhere, made the frame for them to sit in, I had another purpose in mind but they r spare now

with the wider roller it offers more support to the board being cut

After looking at this for most of today I'm thinking I am gonna do something different for the greater good of course

120mm drive pulley from memory, not as great a speed change as original but it is faster overall

had to do a bit of work to the adjuster slot and motor shaft slot

I get it - thanks
