Jet JBM-5

[scoly]

Been thinking about a morticer for a while and almost got the HF a week or so ago. Saw an add for the jbm-5 and went to take a look. They had it priced at $125. Looks almost new but only one chisel. Figured chisels were cheap and the price seemed right. Ended up with it for $110. Will have to come up with some projects now.

darned good deal. was that a classified ad or Craig's list? or a refurb?
I think the lowest i've seen was about $175 for new.
Chinese made chisels go for about $7-8
Austrian chisels are supposed to be the best but cost about $16-20

It was in the classified. Man is having a garage sale and said no lookers for the morticer. Had a lot of action on creepers, ladders, etc.

I don't have a link but Hartville Tool had chisels in their clearance section yesterday for a reasonable price.

Thanks Mike! Looked around Hartville's site and found the chisels on sale for $17 and change. Seemed like a good deal. Appreciate the lead.

You might want a 5/16. I find I like a 5/16 better than a 1/4 in 3/4 stock. I got 1/4, 3/8, and 1/2 when I bought my JBM-5 (for about $200) and later added the 5/16 which gets used about as much as any of them. The height extension also came in handy on a couple interior doors.

I do a lot more mortise and tenon joints now.

Jim

What height extension?

[LCHIEN]

What height extension?

they sell a riser that extends the column height by a few inches.
So you can work on thicker stock (although it doesn't increase the mortising maximum depth any.)

[BigguyZ]

Ok, I figured as much but wasn't sure. I've seen people mount the base plate backwards, and then build up the base with layers of plywood. Mostly this is done to make up for depth lost using an XY vise. I was thinking of doing just that type of thing.

[JimD]

I think the riser was only about $20. It is cast iron and comes with longer bolts. It acts as a 2 inch spacer between the bottom of the column and the base. Very simple but when you can't get the door stile between the mortise chisel and the base.... Loring is also correct that it does not increase the throw of the mortiser any.

Turning the mortiser around should also work but then you would need to rig up a table of some sort too.
