Convert 6" bandsaw to 9" depth of cut

[Newbie_Neil]

Hi SF

Tony, Looks like you might have started a trend here. I've got visions of members up and down the country taking tools to their bandsaws to make them ever bigger and better than before!
Cunning plan on your part, though. Bloody good one, in fact!

I'm sorry but I have to give you a public warning for this post. You must never ever post in this vein again.

It doesn't say so, but Tony made a jig for this job. :shock: Now, do you see why I am so concerned?

You only need to give Tony the slightest encouragement and we will all be made to pay. We'll have jigs coming out of our ears for months. :lol:

Oh, woe is me. :wink:

Cheers
Neil

Now, now, Tony, put that MDF and threaded insert down and come quietly. What's that your muttering under your breath while menacingly hefting that aluminium T-track in your hand? Oh. That's not a very nice thing to say about Neil, is it...?

Cheers, Alf :wink:

Would a jig extend to my new trench cutting guide system (mk2) or the dust extraction support for the pillar drill (that Hannah helped with) or my circle making device to make perfectly round wheels or mods to kit to make it work better or....... I guess not


I'll get the coat...

ROTFL.

I rest my case. :roll:

Cheers

Hi Tony

OK, I'll bite. Do you have any photographs?

Cheers
Neil

PS What have I done? :shock:

the dust extraction support for the pillar drill (that Hannah helped with)

Oh Hannah, no. Shame on you for encouraging your dad in these evil ways. :roll:

PS What have I done? :shock:

Lost your marbles? :wink:

Cheers, Alf

Not completed yet due to university work getting in the way of fun but soon...

Problem with the last one was dust extraction (a big thing with me at the moment is dust collection) and the new one solves that along with an improved clamp and guide

Hi Tony

I'll look forward to seeing it.

Cheers

I can't see the images in this post is it me or is it just because it's an old post.

The images are no longer available because the original links were image hosting locations that have either been moved/deleted or server shut down.

Ta.

Quite likely as this is a very old post. If you tell me what you want to see i will see if I can take the photos for you. I have the bandsaw now.

Ok, Correction: it was just a membership issue with original poster ID, Tony still has the pictures hosted.

Hi all

It's Bean's fault really.

He was expressing love and admiratione for my bandsaw (well, he said he liked it) and asked if there were any problems.

Well, yes, the resaw height is ONLY 6" which is annoying :evil: says I.

Two engineers faced with a problem!!! After a brief discussion and a bit of measuring, work started and now my bandsaw will resaw a FULL 9" depth!!!!

I originally thought that I might have to reinforce the section around the aluminium extrusion (already decided how) that holds the bearings but this has proved not to be the case as the sheet steel that the case is made from is quite thick and the door locks tight providing additional support. The defection in the ali extrusion when I push against it by hand is the same afer the mod as it was before

Bandsaw is Charnwood W720 155mm. Standard chinese job which is sold under many brand names

Here's what I did

Before (note ruler at 155mm depth of cut)

I removed the blade and top wheel first. Now I modified the aluminium section that holds the blade guides first by shortening it slightly and cutting a little shoulder at the top. Also had to remove some material from the slot (see picture where wheel runs through ali) to allow the top wheel to run through the ali.

Next, I got the angle grinder out and cut a profile in the rear to accept the bearing assembly when fully raised

I also made a small cutout in the side and redrilled the holes to mount the internal channel that guides the ali extrusion when lowering and raising the bearings. Also re-drilled the clamp bolt hole a little higher and slightly modified the steel that sits at the other end of the bolt by cutting 12mm from the bottom of it

I had to file a coutersink along the slot that originally held the caphead bolts that secured the bearing guides to the end of the extrusion. I fitted 6mm countersunk bolts in it.

Here you can see the 9" depth of cut and I have placed the same ruler from the first picture in shot too for reference

First resaw operation was 7 1/2" Beech. Lovely

OK. Pretty easy and the result is 50% more depth of cut. Used a hacksaw, angle grinder and file + battery drill.

Total time for the job was 4 hours.

I've done similar with my 14" SIP machine, I also moved the lower guide bearing assembly inside the lower cabinet and lowered the table Mounting support about 20mm. The latter mod does mean I loose some of the table angle adjustment but that is not an issue for my turning blank and associated wood cutting.

Cheers for that, that's great, really appreciate the pics.
