I am interested in building an outdoor garden bench with floating tenons. I am curious as to the appropriate size of the tenons. I have access to a slot mortiser with bits of either .6” or .8”....

I would like to create slot mortises of 3/4 thickness with a Hammer A3-31 slot mortiser. The closest bit Birds Mouth Bit size that I can find online is 20 mm. Is the 3 hp motor on the mortiser...

Thank you for all the suggestions!

The ‘Miter Jack’ is a neat idea; but, the complexity of its construction would make the original problem a trivial exercise. However something like the Miter...

Hi

I have a Felder 400 FB bandsaw and I need to perform accurate crosscuts on thick stock (about 2.5”) and about 5” wide.

Usually I do crosscuts by hand and correct with a shooting board; but...

I have recently come to notice a slight concavity on the infeed table of my A3-31 jointer. The concavity is in the direction that is perpendicular to the fence.

The concavity does not seem to...

Hi Jim

Thank you for your response.

I meant I have been using 8 mm not 10 mm — correction

Thanks — Mick and John!

On my next table of 7/8” aprons, I will try to up my float tenon size to 10 mm from 8 mm. I have been using the former.

It is difficult to translate the old rules for...

What are the rules for sizing loose tenons? I am interested in constructing a table by connecting a 7/8” apron to a 2”” table leg with loose tenons. What should the thickness off the tenon be? How...

Just curious— I have constructed a table and I have no reference surface in the home to consider as dead flat for the size of the table. I want to make sure that it sits flat on the floor. Are...

Hi Mark

From your response I am not alone. In the past I have used shooting boards following a cut with the Ulmia and kind of forgotten about the issue. The issue came up again with cutting table...

Generally, different blades cause different directions in the vertically cut

Several years ago, I purchased a new Ulmia 354 mitre saw. I have had mixed results with accuracy— horizontally the accuracy is excellent. Vertically I get mixed results — some times the cut veers to...

Hi Matthew,

The snipe is while planing.

I have not seen instructions in the manual — just curious if there are formal instructions online.

The other concern that I have is the operation of...

Hi Tim,

i have had the Hammer A3 31 with helical cutter head for about a decade. Recently, I have noticed some snipe. Is there any advice or video on how this is to be eliminated?

Also, I am...

Question: where can metric router/mortiser bits be purchased? Domestic suppliers seem to be limited to English units.

Hi,

Has anyone constructed (or bought) a mobility kit for the slot mortiser attachment to the Hammer A3 31 jointer planer.

If so please send a picture and any additional information about the...

Kevin,

Thank you — I think what you suggest will work after a few trys!

I have a problem routing mortises with Slot mortiser. Because of my technique or lack thereof the mortises in the leg tend to be slightly wider than those in aprons. This makes for a loose fit in the...
